Antananarivo, also known by its colonial shorthand form Tana, is the capital and largest city of Madagascar. The administrative area of the city, known as Antananarivo-Renivohitra, is the capital of Analamanga region. The city sits at 1,280 m (4,199 ft) above sea level in the center of the island, the highest national capital by elevation among the island countries. It has been the country's largest population center since at least the 18th century. The presidency, National Assembly, Senate and Supreme Court are located there, as are 21 diplomatic missions and the headquarters of many national and international businesses and NGOs. It has more universities, nightclubs, art venues, and medical services than any city on the island. Several national and local sports teams, including the championship-winning national rugby team, the Makis, are based here.

Andrianampoinimerina (1745–1810) ruled the Kingdom of Imerina on Madagascar from 1787 until his death. His reign was marked by the reunification of Imerina following 77 years of civil war, and the subsequent expansion of his kingdom into neighboring territories, thereby initiating the unification of Madagascar under Merina rule. Andrianampoinimerina is a cultural hero and holds near mythic status among the Merina people, and is considered one of the greatest military and political leaders in the history of Madagascar.
